W/K.{Mr Kilner} To Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} from Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} c. c. to G.Gardiner (Paris) 200a. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}1/AP.30.1.37. 6.B.IV. REPLACEMENTS. We are sending out a standard front axle fitted with aluminium drums, for the above car. This axle has steering levers too short for aluminium drums, and you may notice an occasional scraping noise when manoeuvring the car due to the cross steering tube fouling the drums. This will not matter. We have no more long levers to give you. We understand you have scrapped both of the front drums. They were both special, it being hoped that they would not crackle. If either of them remains intact please run it and return the drum we are now sending out on the axle. As regards the rear drums, we are short of these also and the pair we have sent you have Lepaz liners. They are also all we have until we can make more; Hs.{Lord Ernest Hives - Chair} is interested in Lepaz. Please watch them carefully, the stress Lepaz sets up in the aluminium is rather higher than normal. Please make certain when the car is rebuilt that the front brakes work when the rear brakes are dis-connected. Gardner shows now they should be set. The stopping distance of the car from 30 m.p.h. is the same when the front brakes only are used, or our normal hand brake; from higher speeds the former system is better as the servo lag is constant.
